Abstract
A passenger seat for a passenger vehicle including but not limited to an aircraft may include a seat base, a seat back, and an energy absorption system. The energy absorption system is spherically coupled to the seat base and spherically coupled to the seat back, and includes a dampening member and a support assembly. The dampening member is movable relative to the support assembly responsive to a load applied on the seat back such that engagement between the support assembly and the dampening member dampens the load.
